I hope this is the right forum for this, but does the v-rod ecm use a Knock sensor of any type?

the reason I ask is I have seen some crazy lean dyno graphs posted on this site. With my background of late model gm motors, some of the AFR numbers i have seen have made my stomach just turn.

so enlighten me just what do we have to work with when it comes to these things and tuning.

Yes, the stock ECM uses a patented ion knock sensor ther retards the timing when knocking is detected.
